Osmium isotopes in hydrothermal £uids from the Juan de Fuca Ridge
We present Os data for axial high-temperature and off-axial low-temperature hydrothermal solutions from the Juan de Fuca Ridge. The high-temperature, H2S-bearing axial fluids have unradiogenic Os isotopes pointing to a nearly complete domination of osmium isotopes from the basalts during hydrothermal circulation. The ridge axis fluids typically do not show large enrichment in osmium concentrati...
متن کاملDissolved inorganic carbon isotopic composition of low-temperature axial and ridge-flank hydrothermal fluids of the Juan de Fuca Ridge
We analyzed stable carbon (δC) and radiocarbon (ΔC) isotopes of ocean crustal fluid samples from two low-temperature environments on and near the Juan de Fuca Ridge (JDFR), a seafloor spreading center in the northeastern Pacific Ocean. Themajor goals of this work were to resolve relative dissolved inorganic carbon (DIC) sources and removal processes, and characterize the isotopic signatures of ...

متن کاملMetagenome sequencing and 98 microbial genomes from Juan de Fuca Ridge flank subsurface fluids
The global deep subsurface biosphere is one of the largest reservoirs for microbial life on our planet. This study takes advantage of new sampling technologies and couples them with improvements to DNA sequencing and associated informatics tools to reconstruct the genomes of uncultivated Bacteria and Archaea from fluids collected deep within the Juan de Fuca Ridge subseafloor. Here, we generate...
متن کاملHydrothermal circulation within topographically rough basaltic basement on the Juan de Fuca Ridge flank
[1] We use coupled heat and mass transport models to investigate the basement permeability distribution and hydrothermal circulation patterns in an area with large basement relief below flat seafloor on the eastern flank of the Juan de Fuca Ridge. If heat transport around Ocean Drilling Program Sites 1026 and 1027 were purely conductive, the top of basement at Site 1027 (below 600 m of sediment...
